Augustus is doing rather well for himself. His bills are all paid in full and he has extra money every month that he's decided should really be invested to help better prepare himself for his retirement. He's decided that he's going to save $24,000 per year. He's done a lot of research and found an investment that looks right for him. It pays 5% interest annually. He's decided that he'll save for the next 18 years as he'll probably be ready to retire then. If the account compounds his money annually how much will Augustus have saved at the end of 18 years?
